# Fetch latest updates from GitHub
git fetch
# Create a new branch
git switch --create backport-14078-to-k218 origin/k218
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x 20ac1bacd89228fb863a6b0a3e574e27368cf9b0

If you have the GitHub CLI installed:

# Push the branch to GitHub:
git push --set-upstream origin backport-14078-to-k218
# Create the PR body template
PR_BODY=$(gh pr view 14078 --json body --template 'Backport 20ac1bacd89228fb863a6b0a3e574e27368cf9b0 from #14078{{ "\n\n---\n\n" }}{{ index . "body" }}')
